getAllEdges

public static java.util.List<EdgeValue> getAllEdges(pl.psnc.graph.model.type.IResourceDecorator startResource,
                                                    pl.psnc.graph.model.type.IResourceDecorator endResource,
                                                    java.util.List<EdgeValue> edgeList)

Get list of all the matching edges between two given graph nodes or null if no matching pair was found. If any of the given nodes is null null is returned.

Parameters:

startResource - start resource, which defines beginning of the edge

endResource - end resource, which defines edge end

edgeList - the list of edges

Returns:

list of all the matching edges between two given graph nodes

getStartEdge

public static EdgeValue getStartEdge(pl.psnc.graph.model.type.IResourceDecorator endResource,
                                     java.util.List<EdgeValue> edgeList)

Get first matching start edge going to given resource or null if no matching pair was found

Parameters:

endResource - end resource, which defines edge end

edgeList - the list of edges

Returns:

first matching start edge going to given resource

getEndEdge

public static EdgeValue getEndEdge(pl.psnc.graph.model.type.IResourceDecorator startResource,
                                   java.util.List<EdgeValue> edgeList)

Get first matching end edge going from the given resource or null if no matching pair was found

Parameters:

startResource - start resource, which defines beginning of the edge

edgeList - the list of edges

Returns:

first matching end edge going from the given resource
